Create, Read, Update, and Delete (CRUD) actions are readily available via Flow steps; these steps, commonly called "methods" by programmers, are auto-generated by Data Structures capable of writing to a database. Articles in this subcategory will review the use of these steps for each supporting Data Structure.
